Lyric Williams. I. ntroduction. In our PowerPoint Presentation, we will be explaining what alkaline earth metals are and some of their uses, reactions, properties, etc. . We will tell what the four metals in the group are, and their mass, density, and melting point are. . 30. th. April 2012. 1. Dubai continues to play an important role in the Gold trade. The Gold business, has witnessed very strong growth in Dubai over the past decade. World supply of gold in 2011 was ~ 4000 . Chapter 4.10,4.11 and 5. Combining Elements. When we begin combining elements we make compounds.. Two types. Non-metal and metal. Non-metal and non-metal. Each type has unique physical and chemical properties. Why are metals used to make these items?. Properties of metals . What property of metals is being . utalised. in the images on the previous slide?. Fishing sinker. Cooking pot. Electrical wires. Bread ties. The abundance of the metals in the Earth's surface varies greatly.. Only metals that occur in concentrated deposits - called ores - are economically valuable.. About 23,000 kg of materials are extracted from the surface and processed per person in our country each year.. Anthony Cosimano. Elements on the lower periodic table found in the earth’s crust.
